RCW 10.31.100

Arrest without warrant.

A police officer having probable cause to believe that a person has committed or is committing a felony shall have the authority to arrest the person without a warrant. A police officer may arrest a person without a warrant for committing a misdemeanor or gross misdemeanor only when the offense is committed in the presence of an officer, except as provided in subsections (1) through (11) of this section.

(1) Any police officer having probable cause to believe that a person has committed or is committing a misdemeanor or gross misdemeanor, involving physical harm or threats of harm to any person or property or the unlawful taking of property or involving the use or possession of cannabis, or involving the acquisition, possession, or consumption of alcohol by a person under the age of twenty-one years under RCW 66.44.270, or involving criminal trespass under RCW 9A.52.070 or 9A.52.080, shall have the authority to arrest the person.

(2) A police officer shall arrest and take into custody, pending release on bail, personal recognizance, or court order, a person without a warrant when the officer has probable cause to believe that:

(a) An order has been issued of which the person has knowledge under RCW 26.44.063, or chapter 7.92, 7.90, 9A.46, 10.99, 26.09, 26.10, 26.26, 26.50, or 74.34 RCW restraining the person and the person has violated the terms of the order restraining the person from acts or threats of violence, or restraining the person from going onto the grounds of or entering a residence, workplace, school, or day care, or prohibiting the person from knowingly coming within, or knowingly remaining within, a specified distance of a location or, in the case of an order issued under RCW 26.44.063, imposing any other restrictions or conditions upon the person; or

(b) A foreign protection order, as defined in RCW 26.52.010, has been issued of which the person under restraint has knowledge and the person under restraint has violated a provision of the foreign protection order prohibiting the person under restraint from contacting or communicating with another person, or excluding the person under restraint from a residence, workplace, school, or day care, or prohibiting the person from knowingly coming within, or knowingly remaining within, a specified distance of a location, or a violation of any provision for which the foreign protection order specifically indicates that a violation will be a crime; or

(c) The person is eighteen years or older and within the preceding four hours has assaulted a family or household member as defined in RCW 10.99.020 and the officer believes: (i) A felonious assault has occurred; (ii) an assault has occurred which has resulted in bodily injury to the victim, whether the injury is observable by the responding officer or not; or (iii) that any physical action has occurred which was intended to cause another person reasonably to fear imminent serious bodily injury or death. Bodily injury means physical pain, illness, or an impairment of physical condition. When the officer has probable cause to believe that family or household members have assaulted each other, the officer is not required to arrest both persons. The officer shall arrest the person whom the officer believes to be the primary physical aggressor. In making this determination, the officer shall make every reasonable effort to consider: (A) The intent to protect victims of domestic violence under RCW 10.99.010; (B) the comparative extent of injuries inflicted or serious threats creating fear of physical injury; and (C) the history of domestic violence of each person involved, including whether the conduct was part of an ongoing pattern of abuse.

(a) RCW 46.52.010, relating to duty on striking an unattended car or other property;

(6) Any police officer having probable cause to believe that a person has committed or is committing a violation of RCW 79A.60.040 shall have the authority to arrest the person.

(7) An officer may act upon the request of a law enforcement officer in whose presence a traffic infraction was committed, to stop, detain, arrest, or issue a notice of traffic infraction to the driver who is believed to have committed the infraction. The request by the witnessing officer shall give an officer the authority to take appropriate action under the laws of the state of Washington.

(11) A police officer having probable cause to believe that a person illegally possesses or illegally has possessed a firearm or other dangerous weapon on private or public elementary or secondary school premises shall have the authority to arrest the person.

For purposes of this subsection, the term "firearm" has the meaning defined in RCW 9.41.010 and the term "dangerous weapon" has the meaning defined in RCW 9.41.250 and 9.41.280(1) (c) through (e).

(15) No police officer may be held criminally or civilly liable for making an arrest pursuant to subsection (2) or (9) of this section if the police officer acts in good faith and without malice.

(16)(a) Except as provided in (b) of this subsection, a police officer shall arrest and keep in custody, until release by a judicial officer on bail, personal recognizance, or court order, a person without a warrant when the officer has probable cause to believe that the person has violated RCW 46.61.502 or 46.61.504 or an equivalent local ordinance and the police officer: (i) Has knowledge that the person has a prior offense as defined in RCW 46.61.5055 within ten years; or (ii) has knowledge, based on a review of the information available to the officer at the time of arrest, that the person is charged with or is awaiting arraignment for an offense that would qualify as a prior offense as defined in RCW 46.61.5055 if it were a conviction.

(b) A police officer is not required to keep in custody a person under (a) of this subsection if the person requires immediate medical attention and is admitted to a hospital.

Intent—2010 c 274: "The legislature intends to improve the lives of persons who suffer from the adverse effects of domestic violence and to require reasonable, coordinated measures to prevent domestic violence from occurring. The legislature intends to give law enforcement and the courts better tools to identify violent perpetrators of domestic violence and hold them accountable. The legislature intends to: Increase the safety afforded to individuals who seek protection of public and private agencies involved in domestic violence prevention; improve the ability of agencies to address the needs of victims and their children and the delivery of services; upgrade the quality of treatment programs; and enhance the ability of the justice system to respond quickly and fairly to domestic violence. In order to improve the lives of persons who have, or may suffer, the effects of domestic violence the legislature intends to achieve more uniformity in the decision-making processes at public and private agencies that address domestic violence by reducing inconsistencies and duplications allowing domestic violence victims to achieve safety and stability in their lives."
